报错：Ambiguous mapping

java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'testController' method 

public java.lang.String wt.maven.example.controller.TestController.sessionDestroy(javax.servlet.http.HttpServletRequest)
to {[/test/session]}: There is already 'testController' bean method

原因：该控制器下有两个相同的url，导致spring容器不知道该url映射到哪个方法。
